Stuffing perk - Is it even possible to damage your leg armor?

I want to activate stuffing perk for my leg armor, but I can’t damage it no matter what. Leg armors in this game are useless as the NPC never aims for your legs, so you can basically run in your underwear while wearing full upper body armor set.

Yeah, getting legs damaged is a bit difficult. I’ve only managed that while attacking from horseback.
